Bengali

The name 'Bengali' directly refers to the Bengal region of the Indian subcontinent. The term 'Bengal' itself is derived from the Sanskrit word 'Vangala' or 'Vanga,' which historically referred to a kingdom or region in the eastern part of the Indian subcontinent. The name is primarily used as a demonym, indicating a person or thing from Bengal, rather than a traditional given name.

While not commonly used as a personal given name in the Western sense, 'Bengali' can be adopted as a surname or a descriptive term. In the context of personal names, it would typically be used to denote a person's ethnic or geographic origin, similar to how 'Irish' or 'French' might be used descriptively. Its usage as a first name is extremely rare and would likely be a modern, unconventional choice.
